APPARATUS FOR PRODUCING To all whom it may. concern Be it known that I, Smornmn Hum, a subject of the Emperor of Austriaungary,3 residing at Chicago,in the county of Cook} and State of Illinois, have invented certain new and useful Improvements in Apparatusfor Producing Ozone, of which the followbeing deemed unn ece'ssary. to either show or 1 ing is a specification.

This invention relates to improvements. in an apparatus for producing ozone, and particularly to the electrodes thereof, and it consists-in certain peculiarities of the con-'. struction, novel arrangement .and operation of the various part-s thereof, as will be hereinafter more fully set forth and specifically v claimed.

The principal object of the invention is toprovide an apparatus for producing ozone, or vozonizing air by means of the discharge of electric current of high potential, which shall be simple and inexpensive in construction, strong, durable, compact in form, efficlent in operation, and so made that it may be, if desired, readily connected to the ordinary 110 volt electric light circuit, and thus be conveniently used, or to any suitable source of electric supply for furnishing current of the required tension to the electrodes.

Another object is to so construct, arrange, and support the electrodes used to produce the electrical discharges, and their connecting parts, thatthey can be readily placed in operative position in the apparatus on easily removed therefrom for the purpose of permitting them to be cleaned.

A further object is to so support and arrange the electrodes that their number may be varied in a given sized apparatus to produce the resultrequired, thereby varying the capacityv of the machine by simply increasing or diminishing the number of electrodes. Still another object'is tolprovide means whereby the various elements of the apparatus willge compactly incased in their operative positions for shipment and use, without danger of impairment by accidental disconnection of the parts, particularly of the conductors leading from the transformer to the electrodes, and so that the machine can be electrically connected for use by persons who are not skilled electricians.

Other objects and advantages of the. in-

" vention will be disclosed in the subjoined description and explanation.

As the invention resides -mainly in the construction, arrangement, and mounting or suppor;t of .the electrodes and their connectmg parts, I have shown said parts only in dcta1l,.and willhereinafter particularly descrlbe the same, referring to the other parts of the apparatus in age'neral way only, it

Fig. 2, is a detached side view of the supporting frame for the electrodes, showing the Patented Mas-25.19113.

Fig. 3, is aside viewof a pair of the electrodes showing them sepunited by a piece of glass and illustrating the manner of holding the electrodes at slight distances from the pieces of glass, yet in parallelism therewith. Fig. 4, is a view of the supporting frame for the electrodes looking from one end thereof, and showing the electrodes mounted thereon. Fig. 5, is a fragmental perspective" viewof a portion of one of the electrodes showing the means employed for spacing the same from-the pieces of glass whichv are interposed between the electrodes, and Fig. 6, is a View in side elevation of a pair of electrodes illustrating a modification in their construction. v

Like-numerals of reference refer to corre sponding parts throughout thedifi'erentterial, but preferably of wood, and-rectangu lar in shape as shown; This casing is pro-' vided with a base 11, on which is mounted near one of its ends an electric motor"12, or

rotary converter, as the case may be, .of'the ordinary or any preferred construction, which drives a :Ean 13,.m9unted (m the shait.

the air as it passes through said opening.

Mounted on the base 11, of the casing at about its middle is a transformer 18, ofthe ordinary or any preferred construction, which is electrically connected to the motor 12, in the usual manner by means of conductors 19, and 20, the shaft of which motor may be provided with an interrupter of other group, while the reference numeral the ordinary kind, not shown.

Leading from a suitable source of electrical supply, not shown, and through suit able opemngs in the casing, which open-= ings are also not shown, and electricallyconnected to the motor in the usual manner are conductors 21, and 22, which supply I the apparatus with electrical energy.

Mounted on the base 11, near one end thereof, which will be termed the discharging end, is the supporting frame for the electrodes, which frame is designated as a whole, by the reference numeral 23, and includes a pair of uprights 24, and 25, which are firmly secured at their lower ends to thebase of the casing. Each of the uprights 24, and 25, of the electrode supporting frame is provided with upper and lower brackets or arms 26, and 27, respectively, which brackets are extended horizontally from said uprights and longitudinally with respect to the casing, so that the arms on one of said uprights will be inparallelism with the arms on the other upright, and a pair of said arms will be located near each made of insulating material.

Located between the bars 33, on the up er side of the casing. Connecting the arms 26, is a horizontally disposed screw-threaded rod 28, and connecting the arms 27, is a similar rod 29, which rods are preferably made of fiber. Transversely uniting the uprights 24, and 25, are screw threaded rods 30, and 31, which are alsov preferably made of fiber and are located so that the rod 30, will lie in a plane with the rod 28, while the rod 31, will lie in a plane with the rod 29. Mo'vably mounted on the rods 28, and 30, and adjustably he (1 thereon by means of nuts 32,, are a pair of bars 33, which are preferably made of fiber or other non electric conducting material. Movably mounted and adjustably held on the rods 29, and 31, by means of nuts 34, on said rods are a pair of bars 35, which are also rods of the supporting frame for the e ectrodes, and between the bars 35, on the lower rods of said franie are a series of electrodes and a number of pieces of glass which are interposed between said electrodes, the whole being pressed toward each other and held in spaced relation to one another by means of the bars 33, and 35, which can be adjusted on their respective rods by means of the nuts 32, and 34, on said rods and by means of projections formed on the elec trodes as will be presently explained. The said electrodes are all of the same construction, but as one group thereof is in electric connection with one pole and the other, is in connection with the other pole, said groups will be designated by different characters, for instance, the reference numeral 36, designates the electrodes of one of the groups" and the numeral 37, the electrodes of the 38, deslgnates the pieces or plates of glass which are interposed between the electrodes and are located onthe outside of the outermost electrodes. As is clearly shown, in Fig. 3, of the drawings, each of the electrodes consists of a main or body portion 39, having at one of ends arms 40, and 41, which are disposed in opposite directions and at substantially right angles to the body of the electrode. Each of the arms 40, and 41, is provided with an'open slot or recess 42, to receive a pair of the rods of the supporting frame. These slots or recesses are preferably inclined in the same direction as is clearlyshown in Fig. 3, of the'drawing, to facilitate the positioning of the electrodes. At its opposite end from the i arms 40 and 41, the body 39, is provided with a longitudinal extension 43, which is preferably reduced as shown, and said extensions project beyond the ends of the glass pieces 38, or plates for the purpose to be presently explained. Each of the electrodes, which are preferably made of. aluminum, is provided with a series of projections 44, and 45, which are formed by indenting the electrodes on opposite sides, thus producing the projections 44, and 45, which are disposed on opposite sides of the electrodes, as will be clearly understood by reference to Figs. 3, 4, and 5, of thedrawings, so that when the electrodes and pieces of glass are placed in their operative positions on the supportingframe, said projections will rest against the surfaces of the glass pieces and hold them at a slight distance from the electrodes so as to permit the passage of airbe tween the glass plates and electrode. The projections 44, and 45, are preferably arran ed in groups, one group near each" of t e ends of the electrodes and the other 13.5

near the middle thereof as is clearly shown in Figs. 3, and 6, of the'drawings. Byforming the electrodes with indentations on oposite surfaces thereof and with corresponding projections, it. is evident that as these affording portions to which clamps maybe 1. In an apparatus for producing ozone, 5
